T0 all whom t may concern Be it known that I-,.ROBERT H. RoNnY, a citizen of the United States, residing atl Burlington, in the county of Alamance and State of North Carolina, have invented a new and useful Hinge, of which the following is a specificatie The present invention appertains to hinges, and more particularly to those employed in connection with window blinds.

It is the object of the present invention to provide a novel and improved set of hinges for a blind, the upper and lower hinges cooperating to ordinarily prevent the detachment of the blind, and to lock the blind when swung completely open.

Another object of the present invention is to provide a set of hinges cooperating in a peculiar or unique manner, to require a predetermined manipulation of the blind to detach the blind from the window frame to which it is hinged, in order that the blind will not be liable to accidentally become disengaged from the window frame.

lilith the foregoing' and other objects in view, which will be apparent as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within t-he scope of what is claimed without departing from the spirit of the4 invention.

The invention has been illustratedin its preferred embodiment in the accompanying drawing, wherein Figure 1 is a fragmental elevation of a. window frame and blind having the improved hinges applied thereto. Fig. 2 is a fragmentalelevation of the blind and hinge lea-ves, the hinge leaves lof the window frame being shown in section. Fig. 3 is al perspective view of that leaf of the upper hinge which is attached to thewindow frame. Fig. 4e is a view, partly in section, of that leaf of the lower hinge which is secured to the blind. Fig. 5 is a perspective view of that leaf of the upper hinge which is secured to the blind. Fig. 6 is a perspective view of that leaf of the lower hinge which 1s secured to the window frame. Fig. 7 is a perspective of that leaf of the lowerV hinge which is secured to the blin In the drawings, the window frame or casinghas been designated .by the numeral 6, and the blind, by the numeral 5. The blind, or rather t-he stile thereof, is swingably jconnectedto the jamb of the window frame by means of the upper hinge A-B and by the lower hinge C-D. These hinges are of peculiar construction, and coperate in a unique manner, to carry out the functions desired.

The upper hinge A-B embodiesY the leaves or plates 7 and 11, respectively, which are secured to the blind and window frame. The leaf 7 is provided with the apertures 8 through which screws may be passed to take int-o the blind, and the leaf 11 is provided with similar apertures 12 for the passage of screws or other securing members to take into the window frame. The leaf 11 is provided with a horizontal ear 13 intermediate its upper and lower edges, the ear being provided with an upstanding pintle 14. For convenience in locating the several parts the adjoining ends of the respective leaves will be termedl the inner ends and the remote ends of the leaves will be termed the outer ends. The ear 13 projects inwardly from the leaf 11,'and t-he leaf 7 is provided with a horizontal eye v9 engagingloosely over the pintle 14 and normally yseating or restingon the ear 13, the eye 9 projecting inwardly slightly from the leaf 7. The ear 13 is pro-` vided with a peripheral notch 15 yat its inner edge, and the leaf 7 `is provided with a lug 10 spaced below the said ear 13. As seen in Figs. 2 and 5, the lug 9 projects from the inner edge of the leaf 7 adjoining the lower edge of the leaf7 the free end of the lug being disposed slightly to theleft of the axis of the pintle and aperture in the eye 9. As clearly seen in Fig. 2the lug 9 stands diagonally to so position the free endof the lug with respect to the pintle and aperture of the eye, for the purpose which will hereinafter appear. It will thus be apparent, that when the blind is swung at right angles to the window frame the free end of the lug will assume a position slightly in advance of the axis of the pintle.

Coming to the lower hinge C-D, the saine embodies the leaves or plates 1G and 21 respectively, which are secured to the blind and window frame. ll'he leaves 1G and 21 are provided with the apertures for the passage of screws to secure the leaves to the respective parts. rEhe leaf 16 which is secured to the blind is provided with a hori- Zontal web 17 intermediate its upper and lower edges, and an inverted socket 18 is attached integrally to the web 17 at the inner end of the leaf 16. The socket 18 is elongated in a plane parallel with the leaf 16 and the sides and inner end of the socket are inclined, the socket being relatively deep at its inner end and decreasing in depth to its outer end. rThe web 17 terminates in a depending latch 22 spaced from the outer end of the leaf 16, the outer end of the web 17 being raised or deflected upwardly to properly position the lug or latch 22. That side of the latch 22 remote from the respective leaf is beveled, as clearly seen in Fig. 7. rlllhe leaf 21 is provided with a horizontal flange 20 intermediate its upper and lower edges, the flange 2O projecting slightly beyond the inner end of the leaf 21, and being provided with an upstanding pintle 19 adjoining its inner end. rlie outer end of the flange 2O is contracted or narrow and merges into an upstanding latch or lug 28, the outer end of the flange being offset downwardly to properly position the latch. That face of the latch remote from the leaf 21 is beveled oppositely to the bevel of the latch 22. It is to be noted that the inner or deeper end of the socket 18 projects slightly beyond the inner end of the leaf 16, the inner end of the socket engaging over the pintle 19, and normally resting on the flange 20 with the tip of the pintle 19 engaging the crest of the socket.

From the foregoing, taken in connection with the drawing, it will be clearly evident that the blind 5 is adapted to readily swing open and closed, and is effectively supported for such movements. Vhen the blind is swung open, the latch 22 is adapted to engage over the latch 23, to lock the blind in open position, it being noted that when the blind is swung open, the momentum thereof will tend to swing the same away from the window frame, and consequently, the latch 22 is adapted to ride over the latch 23 and to drop behind the same. The blind may be readily closed, either from within or without the building or dwelling, by swinging the lower end of the blind parallel with the window frame, as seen in dotted lines in Fig. 2, so that the socket 18 rides upon the pintle 19, and in order that the latch 22 will swing out of engagement with the latch 23. rfhus, the free portion of the blind may be readily swung to closed position, the blind assuming its normal position with respect to the window frame as the blind is swung closed.

Attention is directed to the fact that when the blind is thrown upwardly, due to the latch 22 riding over the lug 23, or due to the manipulation of the blind, the lug 10 of the upper leaf 7 will strike the ear 18 to prevent the socket 18 from becoming disengaged from the pintle 19.

One of the cardinal or salient features of the present invention results from the par ticular positioning of the free end of the lug 10 as above described, rlhus, the lug requires a predetermined operation or manipulation of the blind to detach the same from' the window frame. To detach the blind, the following operation is necessary: The blind must first be swung at right angles to the window frame, which will swing the free end of the lug l() slightly in advance of the axis of the pintle 111, Conse quently, by shifting the blind parallel with the window frame, the free end of the lug cannot pass through the notch 15. lt is therefore necessary to both shift the'blind toward the respective jamb of the window frame, and away from the inner face of the jamb. This is permitted, and also facilitated, by the particular lower hinge, it being noted that the inner end of the flange 2O projects slightly beyond the inner end of the respective leaf, and that the inner end of the socket 18 projects slightly beyond the inner end of the leaf 16, whereby when the blind is swung at right angles to the window frame, the lower portion of the blind may be shifted toward the inner side of the jamb, and then away from the inner side of the jarnb, to properly manipulate the lug 10 so that it can pass through the notch 15. When the blind is thus manipulated, the same may be raised out of engagement with the hinge leaves secured to the window frame. Conversely, it requires the same operation to attach the blind to the window frame, only in a reversed manner, the attachment of the blind to the window frame, however, being rendered much more easy than the detachment of the blind.

What is claimed is The combination of upper and lower hinges for a window blind, each embodying pair of leaves, one of the upper leaves having a horizontal ear provided with an up standing pintle, the other upper leaf having a horizontal eye engaging loosely over the said pintle and normally resting on the said ear, the said ear having a peripheral notch, the second mentioned leaf having a lug spaced below the ear, one of the lower leaves having an upstanding pintle adjoining its inner end, and the other lower leaf having an inverted socket engaging over the last mentioned pintle, the socket being elongated, and being relatively deep at its inner end and decreasing` in depth to its outer end, whereby When the rst mentioned lower and second mentioned upper leaves are swung to a predetermined position With respect to the other leaves and When the socket is slid upon the last mentioned pintle,

the aforesaid lug may aline With the said V10 notoh to pass therethrough.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence ot tWo Witnesses.
